external ornamentation to be seen, but in the distal quarter is an internal structure 

 consisting of oblique fibres. 



Female organs in normal situation. Ovaries tuft-like. 



Spermathecse (fig. 47). Main pouch with nearly globular ampulla and a 

 duct about as long and one third as thick as the ampulla from which it is abruptly 

 set off. From the proximal part of this duct depend two thick, unstalked, kidney- 

 shaped diverticula. These diverticula are nearly smooth externally and show neither 

 distinct incisions nor dilations. After being made semi-transparent by acetic acid 

 they show a rather regular internal division. Both the diverticula of the examined 

 spermatheca contained five seminal chambers regularly arranged in the same plane 

 around the centre of the diverticulum. The seminal chambers opened into the distal 

 end of a common canal which, going somewhat obliquely upwards, entered the proximal 

 part of the duct of the main pouch. The seminal chambers were empty and somewhat 

 collapsed. I think it probable that after being filled with sperm masses they may 

 cause dilations on the external surface of the diverticulum. 



Hab.— Bengal, Saraghat on the Ganges ; R. HODGART leg., 29 — 3o-vi-o6. 



Remarks. — Eutyphoeus bengalensis seems to be nearly allied to E. gammiei 

 ,(BBDD.) from Darjiling, but it is a much more slender form. It differs from 

 E. gammiei principally in the shape of the penialsetse.

Examined seven specimens. 



External Characters« — Dimensions of mature specimens : Length 150 — 190 

 mm., thickness of smallest specimen 3 — 4I mm., of largest specimen 3 — 5| mm., 

 number of segments ca. 215 (in the smallest as well as in the largest specimen). 



Colour dorsally dark violet grey, ventrally dark grey (much changed in preser- 

 vation ?). 



Head tanylobous. Segment 3 divided into two ringlets, the succeeding segments 

 divided into a greater number of ringlets, those just before the clitellum into as many 

 as seven. 



Setae rather small, all at the ventral side of the body, the median dorsal distance 

 being somewhat larger than half the circumference {dd = csL. f u). Setae paired but 

 not very strictly, especially at the ends of the body where they are almost separated. 

 In the postclitellar region aa=ca. 2^ab, bc = ca. i^ab, cd = ab or very little larger. At 

 the ends of the body ab is hardly smaller than be, and be nearly equals cd, aa being dis- 

 tinctly larger than the other distances except the median dorsal (aa =ca. i| ab). 



Dorsal pores present but not visible at the anteclitellar region of the body. 



Clitellum ring-shaped, ventrally somewhat depressed and lower, occupying the 

 segments \ of 13—17 ( =41)-
